epoch time conversion in R
I have a data file where each entry is indexed by the time in seconds since
epoch (e.g. 1046315697). Is there an easy way to convert this time value into
a more friendly time (such as Month-Year) when plotting it?
I searched through the manual, mailing lists, and functions like as.POSIXct
and strptime, but didn't find what I need.
Thanks,
Sharad.
